Zusammenfassung:	PURPOSE: Provided is a resin composition for pipes and tubes for electronic material and industry, which has improved fatigue resistance and chemical resistance and uses an ethylene vinyl acetate resin as a base resin. CONSTITUTION: The resin composition is produced by mixing the ethylene vinyl acetate resin and a resin reinforcing agent, such as a low density polyethylene resin, a linear low density polyethylene resin, an ethylene-propylene-diene rubber(EPDM), or a mixture thereof, in the weight ratio of 95:5-20:80 and adding 0.01-3pts.wt. of a chemical resistant agent, 0.1-0.2pts.wt. of an antioxidant, 0.1-0.2pts.wt. of a UV stabilizer to 100pts.wt. of the mixture of the ethylene vinyl acetate resin and the resin reinforcing agent and then melt-mixing, wherein the ethylene vinyl acetate resin has a melt index of 0.1-10.0g/10min(ASTM D1238, 230deg.C, 2.16kg) and contains 1-50wt% of vinyl acetate.
